Flapping wing micro air vehicles (FWMAVs) are small unmanned aircrafts or flying robots which intended to be used for surveillance, reconnaissance, biochemical sensing, targeting, tracking, etc.To perform such missions, MAVs required do some specific operations as hovering; slow and high speed flying; quick landing take-off, etc.During flapping motion through surrounding air, wings experience inertial aerodynamic forces.For making successful flights in conditions, must have properties flexibility, strength, low weight, long fatigue life, etc.For producing properties, material plays a crucial role.Most of the research related is based on aerodynamics controls.Present materials structural aspects wings.Here carbon fibres skeleton polyethylene membrane.The design 113.8 mm length inspired from giant hummingbird's wing.The sketch was developed gambit software by taking position data, generated using digitizer, printed image hummingbird wing.Developed used, guide, skeleton.The film with adhesive laminated at 150 ºC.Natural frequencies, nature mode shapes, damping characteristics fabricated determined here.
